CHARLES W. BECK, OF ROCKVILLE CENTER, NEW YORK, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO MICHIGAN MOTOR SPECIALTIES COMPANY, OF DETROIT, MICHIGAN, A

CORPORATION OF MICHIGAN.

To all u kom it may concern;

Be it known that I, CHARLES W. BECK, a citizen of the United States, residing at Rockville Center, county of Nassau, State of New York, have invented certain new and useful Improvements in Battery-Boxes, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a perspective view of thebox secured to' the foot-board of an automobile or similar vehicle; Fig. 2 a transverse vortical sectional View of the box'; Fig. 3 a plan I view, the outer cover being removed and the inner cover being shown as partly broken away; Fig. 4 a plan viewof the main receptacle showing the corrugated false bottom;

Fig. 5. a detail View .of a portion of the under side of the inner cover; and Fig. 6 a detail sectional view of a portion of the outer cover showing the spring which is adapted to bear upon the inner cover. I

One of the main objects of this invention is to provide a substantially moisture and dust proof casing in which to carry the dry batteries used on automobiles to provide electric current for the spark or ignition devices of the automobile engine,

It is also the object of this invention to will be insulated from each other, except as they are connected by the usual conductors, and in which they will be insulated from the inclosing casin The. casing is usually of metal and it requently occurs in battery boxes of the ordinary or usual construction that the batteries become electrically connected to the inclosing casing, thereby shortcircuiting and rendering the ignition devices inoperative. In a battery box constructed in accordance with my invention this is practically impossible, thereby not only lengthening the life. .of the batteries, but insuring the proper operation of the electrical spark or ignition means.

Another object ofmy invention is to provide means for yieldingly holding the batteries within the battery box, to prevent undue vibration thereof. By thus yield ingly holding the batteries againstvibration, accidental disconnection of the battery wirescorpenmections is avoided and the batteries the 'lves are not liable to injury. It is well lr that the-inclosing casing Specification of Letters Patent.

provide such a box in which the batteries- BATTERY-BOX.

of the ordinary dry batteries is frequently broken and seriously injured by the movement of the batteries in the battery box. In a box constructed according to my invention vertical movement of the batteries is practically avoided.

Referring to the various parts byinumerals 1 designates the automobile footboard on which the battery box is usually fastened. The box consistsof an outer inclosing receptacle 2 of metal or othersuitable, rigid, water-proof material. The bottom of this receptacle is slightly dished toward the longitudinal center and is pro- Patented Febsil. i mi -3.

vided with an'opening, or a series of openings, 3, to permit of the escape of any water which might collect therein. Within this main receptacle is provided'a false bottom 4 which is corrugated transversely, as "shown clearly in Fig. 3. This bottom is perforated to permit an nwater settling thereon to drain through to the bottom of the main receptacle. The bottom of this receptacle is perforated as at 5 at the corners thereof; and the corners of the false bottom are cut away as at 6 to permit of free access to said perforations, for a purpose which will be hereinafter set forth.

Within the main receptacle, and resting on the false bottom therein,.is an insulating battery holding case 7 This case consists of a wooden bottom 8 which is adapted to rest upon the false bot-tom 4, and a series of upright cells or compartments 9. The vertical walls 10 of the insulating case, forming the cells, are of wood and are secured to the bottom piece 8. Each cell is adapted to receive one battery, as shown clearly in Fig. 3 and each battery is insulated from the adjoining batteries by the walls of the cell containing it, as will be readily understood by reference to Figs. 2 and 3 of the drawings. The upper edges ofthe walls of I '2, Mid is substantially equal in area to the 105 interior of the main casing or container, in order to prevent any material lateral movement' of the lnsulating case. The COIIDBCUIIE vtion from the inclosing casing, I provide a very deep-sided coverl l for said insulating case. The sides of this cover extend into close proximity to the bottom piece 8 of said incloslng casing in order to form a substantially moisture-proof closure for said case. To. the inner surface of the upper Wall of said cover 1 secure an insulatin plate 15, preferably made of wood. This plate is formed with the depending projections 16 which correspond in outline to the form of the cells, and are' adaptedto extend down into said cells and to bear on the upper ends of one. of the pole pieces of the batteries.

As shown in the drawings these projections bear ,upon the upper ends of the carbon pieces 17 of the batteries. These projections are so proportioned that they will contact withthe pole pieces of the batteries before i 0 the main portion of the insulating plate en- ;gage's the upper edge of the insulatin g'ca'se, as shown clearly in Fig. 2. so that theipressure of the inner cover 'will be directly'upon the batteries instead of being taken up by 35 the walls. of the insulating case. y

1 The outer or main casing is provided with -",a covei' 18 to the inner surface of which a f-sp'ri'ng 19j'is secured. When the outer cover 7 is-infplace the spring 19 bears on the inner 4'0 cover14of the insulated case and yieldinglv 1 holds it-in" position and presses it firmly down on the 'c'ai b'on pieces of" the batteries. e innercoverlisprovided, with. a handle I fldhy which; it'may be readily. removed. f The" battery, box is secured to the footboardeof the automobile bva strap 21.v said strapgalso serving to hold the cover of the.

outercfmain receptacle imposition. i It is 'inanifest that by-the construction describedfan'd' shown the batteries will each be insulated from all the other batteries; except as theymay be connected by the usual elec- 'trical connections; and that'the'insulating :[case will be inclosed in a practically dust and moisture-proof casing. It is also obvious that the'batteries will be held against moveme t in their inclosing cells so that accidenta-I disruption" of the batte connectionswiu bepractically-imp'ossib ,e.) Thus flotwo'o'f themost frequent causes 'ofthe fail- ";ure of the 'batterycurrent, namely, accidental disruption 'of'the connections and ,ShOrt circuiting-byreason of injury 'to' the battery cells, or moisture collectir'iginthe tir'batim'y box, are avoided,

The insulating case is readily removable from the main casing and the false bottom loosely rests in the main casing so that it also may be readily removed.- -By this means the case may be-readily cleaned and repaired. I

Having thus described my invention, What I claim as new. and desire to secure by Letters Patent, is:-

1. A battery box comprising an outer casing, an inner insulating case smaller than the interior of the outer casingand formed of a series of cellsto receive the batteries, a cover for the insulating case, an, insulating means secured to the inner side of said cover andadapted to extend down into the cells of the insulating case, a cover for the outer casing, and means to .hold'the inner cover in contact with'the batteries in the cells.
